IPC: B63B25/08
Filed: 1916-06-14
Abstract: 106,351. Morris, H. N., and Turnbull, N. K. June 14, 1916. Vessels for bulk cargoes.-A vessel for transporting liquids in bulk, particularly corrosive liquids such as concentrated sulphuric acid, comprises an outer approximately cylindrical shell and an inner cylindrical tank fitted either concentric with or eccentric to the outer shell. Both the inner tank B and the outer shell A may be divided into a number of compartments by transverse bulkheads C. The outer shell has an horizontal deck D fitted with trunks L, and the inner tank has trunks J extending into trunks K formed on the outer shell. The inner tank, which is intended to receive the corrosive liquid, may be lined with lead, aluminium, cement, or bitumen. The vessel may be wholly or partly submerged by admitting water to the space between the shells and is intended to be towed, the rudder R being operated by the direction of the pull on the tow-rope. According to the Provisional Specification, the inner and outer shells may have a shape other than approximately cylindrical.

Patent GB-724827-A (GB)
Title: Improvements in the preparation of photographic emulsions
IPC: G03C1/04
Filed: 1953-04-01
Abstract: 724,827. Photographic emulsions. KODAK, Ltd. April 1, 1953 [April 1, 1952], No. 9042/63. Class 98 (2). The colloidal binder in silver halide photographic emulsions is a dicarboxylic acid ester of ethyl cellulose or a salt thereof. The dicarboxylic acid is preferably phthalic acid but succinic or maleic acid may be used. The binder may be in the form of its water-soluble ammonium, amine or alkali metal salt. The emulsions are prepared by mixing an aqueous silver halide dispersion containing a silver halide dispersing agent with an aqueous solution of the binder in the form of its watersoluble salt. Suitable silver halide dispersing agents are the ethylene diamine salt of ethyl cellulose phthalate, starch acetate, gelatin, gelatin derivatives such as a phthalate anhydride derivative of gelatin, e.g. as described in Specification 649,544, [Group IV (b)], oxidized protein derivatives or oxidized proteins such as an oxidized casein derivative containing acetyl and acrylonitrile groups (see Specification 648,927) or an ethanolamine cellulose ester compound as described in Specification 410,126, [Group IV ]. The ethyl cellulose phthalate binder preferably has an ethoxy content of at least 42 per cent and a phthalyl content of at least 5 and up to 17 per cent. In the case of low viscosity ethyl cellulose phthalates, a plasticizer such as triacetin or polyethylene glycol may be included in the compositions. The emulsions may be coated on a support such as glass, cellulose ester film, paper, or resin film, and processed with the usual alkaline developers, followed by fixing, preferably in neutral hypo. The emulsion may be treated finally with aqueous acid such as acetic acid, to convert the binder to its water-insoluble acid form, followed by washing with water. In an example, solutions of silver nitrate and potassium bromide and iodide are run into a solution of starch acetate with vigorous stirring, and the resulting dispersion mixed with a 5 per cent aqueous solution of the ammonium salt of ethyl cellulose phthalate at 50‹ F. The suspension thus obtained is forced through a small glass tube into acetic acid giving a threadlike precipitate of the acid form of ethyl cellulose phthalate, carrying silver halide grains. This precipitate is washed with water to remove soluble salts, dried and mixed with distilled water containing starch acetate. The temperature of the slurry thus obtained is adjusted to 55‹ F. and ammonium hydroxide added to convert the ethyl cellulose phthalate to its water-soluble ammonium salt. The emulsion is then spread on glass, subbed with gelatin, and dried. During the drying the salt is converted to the water-insoluble acid form. Specifications 410,125, [Group IV], 649,645 and 649,554, [Group IV (b)], also are referred to.

Abstract: 193,309. Wade, H., (Trescott, C. B.). March 30, 1922. Steam cooking-apparatus.-In low-temperature steam cooking-apparatus the steam is admitted through a reducing-valve 13 to a receiver 12, provided with a waste pipe 35 leading to a steam trap 35<a>, and from thence to the cooking space through a thermostatically operated valve 16, pipe 14 and divergent internal nozzles. The cooking chamber is provided with an insulating jacket, shelves 8 which are accessible through a hinged door, a trapped drain pipe 9, thermometer 10 and a heat-radiating hood 11. The thermostatic regulator comprises a couple 30, 32, enclosed in a casing 31 and suspended from a screwed nipple 21<b>, actuating by a collar 27<a> and points 26 on a lever 25, a spring-pressed lever 22, which closes a jet 23 connected to a fluid-pressure supply, preferably air. A setscrew 24 connects the levers 22, 25. The casing 31 is connected at 34 to the cooking space and is provided with a vent-plug 31<b>. A rise in temperature actuates the thermostat to admit air-pressure to the space 21, and a fall shuts off the air pressure, the action being made more sudden by the air admitted through the plug 31<b> which still further cools the couple. A sectional shaft 27 connected with the collar 27a is provided with an adjusting handle 28. The air-pressure space 21 is connected by a pipe 18 to a chamber having a diaphragm 17 which abuts against a spring-raised valve-stem. 16<a>. A rise in temperature, and consequent admission of air, therefore closes the valve and vice versa. A bleeder-valve 19 is provided. Temperatures of 150-160‹ F. for hams &c. and 200‹ F. for vegetables are used, no thermostat valve being employed in the case of vegetables.

Abstract: 1445819 Meat cutting band saw MEGGITT ENG Ltd 1 March 1974 9360/74 Heading A4C [Also in Division B5] A meat cutting band saw comprises an upper pulley 11, a lower pulley 9, an end-less saw band 7 passing over the pulleys, an electric motor (12) in a main housing 1 for driving the lower pulley and hence the saw band, and a friction brake mechanism including a drum 18 mounted on a drive wheel 16 of the lower pulley 9, a flexible steel band 20 with a friction lining 21 and a solenoid 34, to automatically stop the saw band within 1¢ seconds of the interruption of the power supply to the electric motor either intentionally or when an access door 14 to a waste bin 13 is opened whereby a traction spring 30 connecting the pair of arms 26 to a pair of plates 28 rotates the former about a pin 25 in the anti-clockwise direction, and thereby tightens the steel band 20 around the drum 18 to stop the movement of the saw band. On re-energizing the motor and the solenoid, the armature of the latter connected to a pair of arms 26 turns the arms in the clockwise direction thereby slackening the steel band around the drum 18 and releasing the brake. An access door 10a of the housing 10 is interlocked with the access door 14. The downwardly extending portion of the housing 10 that partly encloses the descending portion of the saw band is adjustable with respect to the upper surface of a stationary table portion 2. In operation, the meat is placed on a carriage 3 movable along guides 4 and is pressed against a guide-member 5 which is displaceable transversely to the direction of the movement of the carriage 3.
